Zinc(II) mineral increased the in vitro, cellular and ex vivo antihyperglycemic and antioxidative pharmacological profile of p-hydroxybenzoic acid upon complexation.

In this study, zinc was complexed with p-hydroxybenzoic acid to synthesize a complex with improved pharmacological profile. Proton NMR and FTIR analysis were used to characterize the complex. Several in vitro, cellular and ex vivo antihyperglycemic and antioxidative assays were used to evaluate the potency of the complex, relative to its precursors, while molecular docking was used to investigate interactions with insulin signaling targets (GLUT-4 and PKB).
